I don't think so. I follow the same canvas than PMIC_INT. I send my
email too fast. The init function was incomplete. Below all I do with
MXT_KEY (PB16) connected to /CHG pin of MXT224.
(Of course, PB16 (CSI_PIXCLK) is not used by another driver)
The problem is not interrupt in Kernel. It is MXT224 that does not send
it. /CHG pin stay High.
I can send you all source code of board declaration if you want.
Thanks a lot.
